Varieties and Planting Material

The variety in the planting hole sets a price ceiling the farmer can never beat. The national average yield was about 400 to 520 kilograms a hectare in 2018 to 2021 estimates, better material and practice lifted project areas from about 200 to 550, and from 3 July 2026 only certified planting material may be sold.
Varieties and planting material · Pillar 01

Ghana's cashew problem starts in the planting hole. Most trees are old, unimproved seedlings that give small nuts and a low kernel outturn, so they earn a low price.

Better planting material is the cheapest, highest-return upgrade in the whole chain, and supplying it is now a protected, policy-backed market. The variety a farmer plants sets a ceiling on the price that farmer can ever earn, and the certified nursery behind that tree is the first place a new entrant should look.

🌰 A large crop that swings with the weather 🌰

Ghana produced about 255,000 tonnes in 2025 on official estimates,1 and officials put 2026 at about 250,000 tonnes against a market estimate near 150,000 tonnes, with official figures possibly including transit nuts.2 The 2025 crop was a recovery from about 161,000 tonnes in 2024, a fall of about 30 percent from about 230,000 tonnes in 2023.3

The crop is grown on about 234,000 hectares (2021/22 figure) by an estimated 200,000 to 400,000 farmers,45 spread across 13 of Ghana’s 16 regions, led by the Bono, Bono East and Ahafo transition zone.4 This transition zone has long been known as Ghana’s breadbasket.

What this shows

Production is rising in trend but volatile year to year: unfavourable weather cut the 2024 crop by about 30 percent.3 For a buyer or processor this means volume cannot be taken for granted, and the businesses that win are those that lock in supply through better trees, irrigation at establishment and farmer contracts.

The breadbasket belt
Ghana's heartland: Cashew grows across 13 of Ghana's 16 regions, concentrated in the Bono, Bono East and Ahafo transition zone, the country's breadbasket.

What this means. A volatile crop means supply has to be built. A better tree gives more nuts and better nuts from the same land, so the planting decision that lifts a farmer's price also steadies a buyer's volume. The sector's reliability is decided in the planting hole as much as in the drying yard.

🌰 Why the variety decision is really a price decision 🌰

Cashew is sold on two quality numbers: the kernel outturn ratio (the weight in pounds of good kernel in an 80 kilogram bag of nuts) and the nut count (how many nuts make a kilogram). Ghana’s 2025/26 price formula rewards a kernel outturn ratio of about 46, a nut count of about 190 a kilogram and moisture of no more than 10 percent.6

Old unimproved trees give small, variable nuts, and quality also depends on the weather: excessive December 2025 rain in Bono and Bono East pushed some nuts down to a kernel outturn ratio of about 42,7 which drags the price a farmer or aggregator can command. Improved clones exist that hit or beat the target, so the variety a farmer plants sets a ceiling on the price that farmer can ever earn.

Better trees raise yield on the same land: grafted and elite material multiplies cashew output per hectare
Figure 1.2 Better trees raise yield on the same land: grafted and elite material multiplies output per hectare
What this shows

Better trees raise yield on the same land. The step from an old seedling to grafted and then elite material multiplies output per hectare, which is why replanting well is the cheapest way to grow the crop.

The gap is wide. Ghana’s average yield was put at about 200 kilograms a hectare in 20128 and at about 400 to 520 kilograms in 2018 to 2021 estimates,9 while improved seedlings and grafts on commercial plantations were estimated at about 350 to 650 kilograms a hectare and grafts from elite mother trees could potentially reach about 800 kilograms a hectare.8

The most credible Ghana benchmark is the African Development Bank Cashew Development Project, which lifted yields from 200 to about 550 kilograms a hectare with better material and practice (Ministry of Food and Agriculture).10 That is nearly a threefold rise on the same land, recorded between 2000 and 2008.

What this means. Read the two numbers together and the variety decision becomes a finance decision. A high-outturn clone lifts both the yield per hectare and the price per bag, so it pays twice, while a cheap unimproved seedling caps both for the life of the tree. The highest-return decision in cashew is taken before the tree is planted.

🌰 What Ghana has to plant: the clone inventory 🌰

Ghana's cocoa and cashew research body, the Cocoa Research Institute of Ghana, has spent two decades selecting and breeding cashew. Three groups of planting material matter for a business decision, and each is chosen for a different trait.

The first are the selection clones, CRIG’s W-series (for example W278, W266, W227 and W044), chosen for vigour, nut yield and nut weight.11 The second are the parental clones, local common-type parents (SG266, SG276 and SG287) crossed with exotic parents, notably BE203 from Benin (tolerant of harsh conditions, high cropping efficiency) and A2 from Brazil (a dwarf type with jumbo nuts above 10 grams).12 The third are the F1 hybrids, improved crosses such as SG287 x BE203, the highest-yielding cross in trials at about 939 kilograms a hectare, and drought-escape crosses with Tanzanian parents (SG266 x TAN992), selected for high flowering intensity in on-farm trials in the Afram Plains.1213

Weight against outturn

A big jumbo nut and a high kernel outturn are different traits pulling in different directions: the grower chooses one for the buyer already lined up.

Research-station trial figures: clone yields are 2013 single-year potentials extrapolated from per-tree yields at 100 trees a hectare; the hybrid yield is years four to six after planting; farm yields are lower.

Sources: Dadzie et al. (2014); Adu-Gyamfi et al. (2020); African Cashew Alliance (2024).

The breeding trade-off to understand is that nut weight and nut yield pull against each other: the genes for a big jumbo nut tend to lower total yield.12 A grower therefore chooses a variety for a specific market. A processor chasing large white wholes wants A2-type jumbo material; a farmer paid on outturn wants a high-kernel-outturn clone such as W278.

🌰 Seed against grafted: a major yield lever 🌰

The other half of the planting decision is how the tree is propagated. Unselected seedlings are cheap but unpredictable: they do not keep the mother tree's qualities and flower late. Grafted seedlings, made by joining a shoot from an elite tree onto a young rootstock, keep the parent's traits and can flower in the first year.

The yield difference is large. Good planting material can lift a tree from three or four kilograms of nuts to as much as fifteen kilograms.14 Grafting is a skilled but low-cost technique, and Ghana research has already worked out the best method, so the constraint is the supply of trained hands and elite scions (the agronomy is covered in Pillar 4).

🌰 Opportunity 🌰
01

Certified grafted-seedling nurseries are the clearest low-capital entry in the whole sector. From 3 July 2026 only TCDA-certified planting material may be sold, yet improved seedlings have long been in short supply,15 and in 2026 the TCDA plans to give more than 3 million free seedlings across six tree crops.16 A nursery that secures scions from CRIG clonal gardens and sells certified grafted seedlings is selling into a protected, undersupplied and policy-driven market. Women-led nurseries already have a track record in this business.14

02

Scion multiplication and clonal gardens. A nursery is only as good as the elite material behind it. Securing scions from CRIG clonal gardens, and multiplying them into new scion banks, supplies the input every certified nursery now depends on.

03

Advisory and matched-variety supply. Because a variety is chosen for a market and a zone, an advisory-plus-certified-scion package, pairing the right clone to the buyer and the agro-ecology, turns a bag of seedlings into a service farmers will pay for.

The rules just changed: certified planting material is now the law. Ghana has moved planting-material quality from advice to regulation. Under the Tree Crops Regulations (L.I. 2471), only TCDA-certified planting material may be sold from 3 July 2026.17 A conveyance certificate system now also governs the movement of cashew, aimed at curbing illegal trading. The 2017 to 2027 Cashew Development Plan aimed to raise production to 300,000 tonnes;15 for 2026 the TCDA plans more than 3 million free seedlings across its six tree crops for over 10,000 farmers.16

For a business, this is the important shift: planting material is no longer a commodity anyone can sell. It is a licensed activity with a quality standard, a certificate trail and a large public buyer. An early entrant that meets the standard can build a lasting business here.

🌰 The risks that sit inside the planting decision 🌰

A farmer holding a handful of small, variable cashew nuts from old unimproved seedling trees

Saved, unimproved or unknown planting material

HIGH
What it is

Planting seed of unknown parentage gives small, variable nuts and a low kernel outturn, which caps the price for the tree's whole 20 to 30 year life.

Evidence

The African Development Bank project lifted yields from about 200 kilograms a hectare to about 550 with improved material and practice (Ministry of Food and Agriculture).10

Who it hits

Farmers who buy the cheapest seedlings, and the aggregators who then handle low-outturn nuts.

How to manage it, and the opening

Buy only TCDA-certified grafted material (compulsory from 3 July 2026); the opening is a certified nursery and scion-multiplication business.

Planting the wrong variety for the market

MEDIUM-HIGH
What it is

A jumbo-nut clone and a high-outturn clone earn from different buyers; planting the wrong one for your market leaves money on the table.

Evidence

Nut weight and yield trade off genetically, and kernel outturn ranges from 22 to 38 percent of nut weight across CRIG clones.1112

Who it hits

Growers who plant without a buyer or an agro-ecology in mind.

How to manage it, and the opening

Match the variety to the market and the zone; sell an advisory-plus-certified-scion package.

🌰 Key takeaways 🌰
01

Ghana grows a large, widely spread cashew crop, about 255,000 tonnes in 2025 on official estimates across about 234,000 hectares and an estimated 200,000 to 400,000 farmers, but it swings sharply with the weather and most of the trees are old, unimproved seedlings.

02

Cashew is sold on two numbers, the kernel outturn ratio and the nut count; the tree sets the ceiling on both, and the weather moves them within a season.

03

The yield gap is wide: the national average was about 400 to 520 kilograms a hectare in 2018 to 2021 estimates, while the African Development Bank project lifted yields from about 200 to about 550 kilograms a hectare with better material and practice.

04

A variety is chosen for a buyer and a zone, because nut weight and nut yield trade off against each other genetically.

05

Cashew's cheapest, highest-return upgrade is the tree itself. Old seedling orchards cap a farmer's price; certified grafted clones lift both yield (well above the 400 to 520 kilogram national average) and kernel outturn (towards the 46 to 48 target). With certified material now compulsory and improved seedlings long in short supply, the nursery, scion-multiplication and clonal-garden businesses are the first place a new entrant should look.

Where this connects. The variety and propagation choice here sets the yield and quality that the agronomy of Pillar 4 either realises or wastes, and the outturn and nut-count grades decided in the planting hole are the same numbers the market reads at the buying station in Pillars 2 and 6. The certified-nursery, scion-multiplication and clonal-garden openings reappear in the entry-point map of Pillar 7, and the year-to-year volatility of the crop is what the post-harvest and processing chapters try to smooth.

Written for each reader

🌰 Practitioner intelligence 🌰

Hover any card to pause and lift it.

For students

If you are thinking of entering, your door is a certified grafted-seedling nursery, which needs only a shade structure, elite scions and a small plot. Learn to graft and to read a clone by its kernel outturn and nut weight, then supply the certified material that, from 3 July 2026, is the only kind nurseries and distributors may sell. The trap first-timers fall into is assuming they must own an orchard; the nursery is the asset-light entry, and it hands you a grafting skill and a farmer network you can build on.

For entrepreneurs

First move: lock a scion source from a CRIG clonal garden and a confirmed order, from a farmer group or a plantation buyer, before you build a single seedbed. Register as a TCDA-certified nursery so you can sell legally after July 2026, and use the old GEPA figure of about GH¢1.50 a grafted seedling (400,000 seedlings for GH¢600,000, before 2020) only as a starting point, and re-cost it at current input prices. The trap that kills first-timers is raising thousands of seedlings with no buyer and watching them outgrow the bags; secure the order first, then propagate to it.

For investors

Diligence asks: is the nursery TCDA-certified and its scion source a verified elite clonal garden; what is the graft-success rate and the confirmed forward order book; and does the buyer pay on delivery or on survival. The thesis is a protected, undersupplied input market created by law, with certified grafted seedlings in short supply since before the 2026 rule. Tie disbursement to confirmed seedling orders and certification, and underwrite the graft-survival risk.

For faculty

Assignment: have students build a variety-selection matrix from Table 1.1, scoring the CRIG clones and crosses on kernel outturn, nut weight and yield for two named buyers, a jumbo-nut kernel processor and an outturn-paid aggregator, then recommend one clone for each with a written justification. Deliverable: a scored matrix plus a short written recommendation. It teaches that a variety is chosen for a specific market.

For ecosystem actors

The lever is to fund and enforce the certified planting-material system: capitalise a private-nursery fund, run certified clonal gardens and scion banks, and police the July 2026 rule at the point of sale. Measure success by the share of new plantings using certified grafted material and by the number of certified nurseries operating. The failure to avoid is subsidising free seedlings of unverified quality, which floods the market with the very low-outturn trees the policy is meant to end.
